Option (B)

Step-by-step explanation:

To determine the length of arc of a circle we use the formula,

Length of arc = $\frac{\theta}{360}(2\pi r)$

Where θ = measure of the central angle subtended by the arc

r = radius of the circle

For the circle given in the picture attached,

Length of arc NM = $\frac{30}{360}(2\pi)(2)$

= $\frac{4\pi }{12}$

= $\frac{\pi }{3}$

Therefore, length of $\widehat{NM}=\frac{\pi }{3}$

Option (B) will be the answer.
